I My invention relates to attachments for the soles of shoes and it hasfor its objectto provide an improved attachment for application to thesole of a golf players shoe and which, when in use, will alTord theplayer better foothold than isv afforded by the ordinary golf playersshoe. It is also an object of this invention to provide an attachmentofthe character described'which will be of simple, inexpensive andelicient construction; which may be quickly applied to or removed fromthe sole of a shoe, and which will be adapted to be iitted to soles ofdifferent sizes.

. To these ends I have provided an attachment for the sole of a shoe,said attachment having the peculiar features of construction andmode ofOperation set forth in the following description,

the several novel features of the invention being separately pointed outand dened in at the close thereof.

In the accompanying drawing: Figure 1 is a bottom plan view .of anattachment constructed in accordance with this invention.V f

Figure 2 is a section on line 2 2 ,of Figure 1. Figure 3 is a section Online 3-'3 of Figure 1. Figure 4 is an elevation, partly broken away, ofa wrench for use in connection with the attachment illustrated inFigures l to 4, inclusive.

The illustrated embodiment of my invention comprises two tread membersindicated generthe claims ally at I and 2, said members being iitted toandV covering the bottom of the forepart of 'the sole of a shoe which isindicated by dotted lines at S in Fig. 3.

The tread member 2 comprises a solid Outer marginal portion 3 formedwitha longitudinal series of threaded holes 4 bordering the outer edge ofsaid tread member while the inner portion of said tread member 2 visformed with a horizontal slot 5 extending from end to end ofisaid mem'-ber, said slot being the space between two walllike extensions 6 and 'Iof the solid outer marginal portion 3.

'I'he tread member I comprises a relatively thick outer side marginalportion 8 and an inner relatively thin blade or wing portion 9 whichoccupies a position within the slot 5 oi member 2 and which is pivotallyconnected adjacent to the toe end of the device to the walls 6 and I ofmember 2 by means of a pintle I0.

At its rear end the tread member I is made with a laterally and inwardlyextending arm Il formed along its inner side with an arcuate rack ofteeth I2 which is concentric with the axis of pintle I 0.

This arm II occupies the slot 5 and its rack of teeth I2 is engaged by apinion I3 havingtrunnions I 4 and I5 journaled in apertures provided inthe walls 6 and 'I of tread member 2. The lowermost trunnion` I5 is madewith a hexagonal extension I6 adapted to receive upon it the lower endof a wrench II, said lower end being made with a hexagonal socket I8 toiit the hexagonal portion I6 Of trunnion I5. Y

When the wrench II is applied to the hexagonal portion I6 of trunnion I5and rotated it acts through pinion I3 and rack I2 to swing the two treadmembers I and 2 relativelyon pintle I0 toward or from each other. 1 v

The tread member 2 is made upon its top side and adjacent to itsperiphery with an upstanding jaw or lug I9 to it against the side of theshoe sole s as indicated inFig. 3, while the tread member I is made uponits top side and adjacent to its peripherywith two upstanding lugsor'jaws I may be made shorter than the spikes 24 ofV tread `member 2.

All ofthe spikes or calks 24 and 26 are made with hexagonal baseportions 2l each of a size to iit `into the socket I8 of wrench I1.

It is a feature of this invention that the spikes or calks 24 and 26 areremovablyl mounted in the threaded holes 4 and` 22 so that I may providewith each attachment a number of spikes of different lengths so thatthe' user of the attachment can incorporate in the device spikes ofthelength suitable for him or spikes of different lengthsasdesired.Frequently a user is best suited with spikes of one length applied tothe tread member I and spikes of another length applied to the treadmember 2, and as will be clear, the wrench II provides an implement bymeans of which the spikes may be quickly applied to Or removed from thetread members. This wrench I1 is also used, as pointed out above, toOperate the pinion I3, which is a matter of considerable convenience.

Between the walls 6 and 1 of tread member 2 and adjacent to the rear endthereof, is a spring detent 3 I, Fig. 1, whose free end pressesyieldingly against the pinion I3 and engages the teeth thereof toprevent rotation of the pinion in one direction. Detent 3l isconstructed with a lateral projection 32 occupying a slot formed in thebottom wall 1 and by means of this projection the detent can be manuallydisengaged from the pinion without removing the device from the shoe.

In applying the attachment to the sole of a shoe it is placed inposition against the forepart of said sole while the two tread members iand 2 occupy more or less separated relationship. Then by means of thewrench Il applied to the hexagonal portion I5 of the trunnion of pinionI3 the latter is rotated in a direction to forcibly swing the two treadmembers together so that their lugs IQ, 20 and 2| are forced against theopposite edges of the sole s'. When the attachment is thus adjusted soas to firmly grip the sole the spring detent serves to lock the parts intheir sole-gripping positions.

What I claim is:

l. An attachment of the character described for application to theforepart of the sole o'I a shoe, said attachment comprising a pair oftread members having their forward ends pivotally connected, one of saidmembers being disposed at one side oi said forepart and made with anarcuate rack of teeth concentric with said pivotal connection and theother of said members being disposed upon the opposite side of saidIorepart, and a member-operating element rotatably mounted on saidlast-mentioned member and meshing with said rack of teeth, said elementbeing operable when rotated in one direction to swing said two membersrelatively toward each other thereby to xedly clamp the attachment totheopposite side edges of said forepart and when rotated in the oppositedirection to swing said two members away from each other.

2. An attachment of the character described for application to theforepart of the sole of a shoe, said attachment comprising a pair oftread members having their forward ends pivotally connected, one of saidmembers being disposed at one side of said forepart and made with anarcuate rack of teeth concentric with said pivotal connection and theother of said members being disposed upon the opposite side of saidforepart, and a'toothed member-operating element rotatably mounted onsaid last-mentioned member and meshing with said rack of teeth, saidelement being operable when rotated in one direction to swing said twomembers relatively toward each other thereby to xedly clamp theattachment to the opposite side edges of said forepart and when rotatedin the opposite direction to swing said two members away from eachother.

3. An attachment of the character described for application to theforepart of the sole of a shoe, said attachment comprising a pair oftread members each provided upon its top side and at its outer edge witha soleaengaging lug and upon its bottom side with a plurality of spikes,one of said members being disposed at one side of said forepart and madeadjacent to its rear end with an arcuate rack of teeth and the other ofsaid members being disposed upon the opposite side of said forepart;means pivotally connecting said members adjacent to their forward endsand with respect to which said arcuate rack of teeth is concentric, anda pinion rotatably mounted on said last-mentioned member and meshingwith said rack of teeth, said pinion being constructed with a trunnionhaving an extension projecting below the bottom of said last-mentionedmember which extension is non-circular in cross section thereby to adaptit for engagement with a wrench by which said pinion is rotated in onedirection to swing said two members relatively toward each other therebyto xedly clamp the attachment to the opposite sides edges of saidiorepart and by which said pinion is rotated in the opposite directionto swing said two members away from each other.

4. An attachment of the character described constructed in accordancewith claim 3 wherein one of said tread members is made with a horizontalslot within which said pinion is mounted, and wherein the other of saidmembers is made with a relatively thin blade occupying said slot and onwhich said arcuate rack of teeth is provided.

5. An attachment of the character described for application to theforepart of the sole of a shoe, said attachment comprising a pair oftread members each provided upon its top side and at its outer edge witha sole-engaging lugr and upon its bottom side with a pluralityof'spikes, one of said members being disposed at one side of saidforepart and made adjacent to its rearend with an arcuate rack of teethand the other of said members being disposed upon 'the opposite side ofsaid forepart and formed withv a horizontal slot into which saidfirstmentioned member extends; means pivotally connecting said membersadjacent to their forward ends and with respect to which said arcuaterack of teeth is concentric; a pinion'rotatably mounted on saidlast-mentioned member within said slot and meshing with said rack ofteeth, said pinion being constructed with a trunnion having anextension'projecting below the bottom of said last-mentioned memberwhich extension is non-circular in cross secz tion thereby to adapt itfor engagement with a Wrench by which said pinion is rotated in onedirection to swing said two members relatively toward each other therebyto fixedly clamp the attachment to the opposite side edges of saidforepart and by which said pinion is rotated inl the opposite directionto swing said two members away from each other, and means adjustablymounted on said last-mentioned tread member and engaging said pinion tolock the latter in its adjusted position.
